Step-by-Step Solution
Introduction to Contraception\nAn ideal contraceptive should be user-friendly, easily available, effective, and reversible with least or no side-effects. It should in no way interfere with the sexual drive, desire, and/or the sexual act of the user. Various methods of birth control are broadly categorized into natural, barriers, IUDs, oral pills, injectables, implants, and surgical methods.
Detailed Categories of Contraception Methods
-
Natural / Traditional Methods:
- These methods work on the principle of avoiding chances of ovum and sperm meeting.
- Periodic Abstinence: Couples avoid or abstain from coitus from day 10 to 17 of the menstrual cycle when ovulation is expected.
- Withdrawal or Coitus Interruptus: Male partner withdraws his penis from the vagina just before ejaculation so as to avoid insemination.
- Lactational Amenorrhea (absence of menstruation): Based on the fact that ovulation does not occur during the period of intense lactation following parturition. This method is effective only up to a maximum period of six months.
-
Barrier Methods:
- In these methods, ovum and sperms are prevented from physically meeting with the help of barriers.
- Condoms: Barriers made of thin rubber/latex sheath used to cover the penis in males or vagina and cervix in females, which also help in preventing STIs.
- Diaphragms, Cervical caps, and Vaults: Barriers made of rubber that are inserted into the female reproductive tract to cover the cervix during coitus.
-
Surgical Methods (Sterilization):
- Also called terminal methods, these are advised for male/female partners as a terminal method to prevent any more pregnancies.
- Vasectomy: A small part of the vas deferens is removed or tied up through a small incision on the scrotum in males.
- Tubectomy: A small part of the fallopian tube is removed or tied up through a small incision in the abdomen or through vagina in females.
